ZR-1 Net Registry Forums - View Single Post - NCRS judging- Non-original exhaust

madmatster · 09-07-2018

I have a nearly stock 1990 Zr1 that has an aftermarket-rusted exhaust i will be replacing. I'm looking for an original unit, but if i cannot find one is there aftermarket option that NCRS judges prefer to see over another? how many pts would I lose for an aftermarket exhaust?

thanks!
